wicked set up, all my years only met two guys that could set up 2 four barrel carbs to work right, not sure I would use now, might know one guy who could. maybe quite tricky to make work together the way they should but when they do ohhhlala and gas milage had best be part of your plan, they like fuel when you open them up,
knew a guy 40 years ago with 428 cobra jet with 2-4"s and he could burn half a tank to bridgewater which was about and hour lol
